Has anyone had trouble with the choke heat stove leaking vaccuum? Just built my stage 1 455 and am having a HUGE leak at the heat stove. What can be done to fix this? Thinking seriously about changing to the earlier style 400/430 manifold. This leak keeps the motor from reving over 2800 rpm, and has created a misfire that can't be easily cured.
There is a gasket they make (did make) for the choke housing on the intake. I would make one if I were you. Where is it leaking from?
